Carbon monoxide poisoning
As you probably know, carbon monoxide is a gas that can be poisonous and has no taste or smell. It can be fatal if you are exposed to high levels of carbon monoxide.
“Carbon monoxide is the odorless, colorless toxic byproduct of burning fuel,” says Ian Tong, MD, chief medical officer for Doctors on Demand. “It competes for space in red blood cells with oxygen. So even a small amount can impact your body’s ability to carry oxygen to the cells. Exposure to this gas can literally poison or suffocate you without warning, but it can also cause numerous symptoms like headaches, dizziness, and nausea.”
Instead, you can install carbon monoxide detectors and try to sit away from your fireplace. Symptoms of carbon monoxide poisoning include headache, dizziness, tiredness, stomach pain, confusion and difficulty breathing. However, your symptoms may be mild when you are away from the source of the carbon monoxide.
